Alnico Bar Magnet, 150 x 15 x 10mm Capacity_5000mL stable Alnico fields and matching

stable Alnico fields and matching keepers across this bar-magnet pair give the classroom a reliable workhorse for ferromagnetism and pole-orientation demonstrations

sized to protect a pair of 50mm (2-inch) bar magnets between lessons and isolate them from steel benchtops
